Nanotechnology for Surgical Success and Phototherapy in Cancer

Scientists at Oregon State University have developed fluorescent nanoparticles that can aid in the removal of malignant tumors and also kill any remaining malignant cancer cells.

Researchers at Oregon State University have developed a new way to selectively insert compounds into cancer cells—a system that will help surgeons identify malignant tissues and then, in combination with phototherapy, kill any remaining cancer cells after a tumor is removed.

It's about as simple as, "If it glows, cut it out." And if a few malignant cells remain, they'll soon die.

The findings, published in the journal Nanoscale, have shown remarkable success in laboratory animals. The concept should allow more accurate surgical removal of solid tumors at the same time it eradicates any remaining cancer cells. In laboratory tests, it completely prevented cancer recurrence after phototherapy.
